STEAM-PI PE-JOINT PACKING.

ELPECIFICATION forming part of Letters Patent No. 332.667, dated December 15, 1885. Application filed September 7, 1885. Serial No. 176,452. (No model.)

To all whom it'may concern.-

Be it known that I, JAMES B. LYONS, of

State of Michigan, have invented a new and Improved Steam-Pipe Joint, of which the fol- My invention relates to the construction of a packing-ring for steam-pipe joints; and it consists of a ring formed-of steel or iron,with sharp concentric bearing-ridges upon each face of the ring,an d in certain details of construction, as will be hereinafter described-,and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a face view of the packing-ring, which is shown as' in .position against one of the flanges, and Fig. 2 is a central sectional view of the joint.

Referring to the construction illustrated in the drawings, A A represent two meeting lengths of pipe, each of which is threaded to engage with an internallythreaded couplingflange,as B B. The flanges B B are united by bolts a a in the ordinary manner, but instead Fig. 2. The novelty of my invention lies in the construction of this ring,which consists, essentially,of

web, 0. The bearing edges 'of these ridges' i are angular or V- shaped,and all the ridges are of vsame height. The'outer diameter of the ring is such that 'it'will fit-closely within the Such being the construction of the parts, it 40 will be seen that the packing-ring may be used upon the ordinary form of flanged coupling.

piece without the slightest alteration of such coupling-pieces.

The ring is more particularly designed for 5 use where thejoint. is subjected to a high degree of heat.

I am aware that a packing has been formed of aplate of rubber having a central opening and concentric flattened ridges on its opposite 50 faces, and I claim no such packing as of my invention. This rubber packing could not be used in places where'intense heat is applied, and moreover when the parts between which the packing is placed are drawn tightly together, the ridges are flattened out, and the plate is virtually a flat plate.

In my construction the ridges are sharp,and, being preferably of steel, will to a certain extent cut into the flanges between which the packing is held.

Having thus fully described myinvention, I claim as new and desire to secure by Letters Patent I p 1. A steel or iron packing ring having two or more angular concentric sharp A-shaped ridges upon each face, a substantially asset forth. V

2. The combination, with the pipes A A, coupling-flanges B B, and bolts a a. of a steel or iron packing-ring, O,formed with sharp shaped ridges i i, substantially as described.
